DRENGHING-TUBE.

Specification of Letters Patent.

Patented Aug. 28,1917.

Application filed February 20, 1917. Serial No. 149,805.

T 0 all whom it may concern:

Be it known that I, ORLANDO CRrrTnN- nnx, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Drenching-Tubes, of which the following is a specification.

This invention relates to veterinary instruments and more particularly to an im provement in drenching tubes. In the use of the ordinary types of drenching tubes ditliculty is frequently experienced in introducing the tube into the mouth of the horse or other animal to which medicine is to be administered in liquid form and even after introduction of the tube it not infrequently happens that a greater or less portion of the dose will be spilled, thereby renderinguneertain the exact quantity which is administered. fore, aims to provide a drenching tube which may be readily and conveniently in troduced into the mouth of the animal and with its discharge end so positioned that the dose of medicine will be delivered directly into the esophagus thus rendering swallowing of the entire dose compulsory.

Another aim of the invention is to so construct the delivery tube of the instrument that the forward or outer section thereof may be conveniently positioned to extend over the animals tongue and with the discharge tip located at;the entrance to the esophagus. I

The invention also aims to provide upon the delivery tube of the instrument, means for limiting the distance to which the tube may be introduced into the animals mouth.

In the accompanying drawing: a

Figure l is a view illustrating the manner in which the implement embodying the present invention is to be employed;

Fig. 2 is a horizontal longitudinal sectional view through the instrument;

Fig. 3 is a side elevation of the instrument;

Fig. 4 is a front elevation thereof;

Fig. 5 is a perspective view of the guard member which is mounted upon the delivery tube of the instrument.

The medicine to be administered is drawn by suction through the delivery tube into the barrel of the instrument which constitutes the container for the medicine and this The present invention, there barrel is cylindrical, as indicated by the numeral l, and may be of any suitable capacity and at one end the said barrel is provided with a removable head 2 having an opening 3 through which is slidably fitted the rod 1 of a plunger which works in the said barrel and fits the same in a liquid tight manner. At its outer end the rod 4:, as is usual, is provided with a handle 6 which may be grasped for the purpose of moving the rod outwardly in order to draw the medicine into the barrel and for the'purpose of forcing the plunger inwardly to discharge the medicine through the delivery tube. The opposite or forward end of the barrel is provided with a removable cap or head 7 into which is threaded one end of the inner section 8 of the delivery tube, the said section at its other end being exteriorly threaded, as at 9, and having fitted thereto one end of an elbow union 10, the intermediate portion of which curves laterally from the said end thereof and extends in such direction a suitable distance, as clearly shown in. Figs. 2 and 4 ofthe drawing. The other end of the elbow union 10 is curved to extend forwardly, as at 11, parallel to the first-mentioned end of the said elbow union and threaded into the end 11 of the union is the inner end of the outer section 12 of the delivery tube. "By reference now to Fig. 2 of the drawing it will be observed that the sections 8 and 12 of the delivery tube extend along parallel lines except that the section 12, at afpoint approximately mid-way beforward portion of the section extends downwardly and also laterally, at a slight angle to the rear portion thereof, as inclicat'ed at 14;

Removably threaded, as at 15, to the forward end of the section 12 is the discharge tip of the tube which is indicated by the numeral 16, the said'tip being'substantially conoidal and formed with a number of perforations 17 through which the medicine may be discharged, the perforations being located preferably inwardly of the end of the tip and suitably spaced about the tip as shown in Figs. 2 and 3.

As before stated, means is provided for limiting the distance to which the tube may be introduced into the mouth of the animal and this means is in the nature of a guard member preferably of the form shown in tween its ends, is bent, as at 13, so that the v Fig. 5 of the drawings. The said guard member comprises a wing 18 and a wing 19, these wings occupying planes at right angles with relation to each other and the wing 19 being formed with an opening 20 threaded to fit the threaded end 9 of the section 8 of the delivery tube with the said wing 19 resting against the inner end of the elbow union 10 and with the wing 18 occupying a plane beside the section 8 at that side thereof beyond which the elbow union projects.

In the use of the instrument, medicine is drawn by suction into the barrel 1 and after a strap has been applied about the animals mouth, as inrFig. 1 of the drawing, the delivery tube is introduced into the animals mouth in such manner that the section 12 of the tube will extend above the middle of the animals tongue with the portion 14: eX- tending downwardly in such manner as to position the discharge tip at the entrance to the esophagus. It will be understood that the section 8 of the tube does not enter the animals mouth but that due to the provision of the elbow 10 this section is permitted to extend beside the animals mouth whereas the section 12 is located within the mouth and above the middle of the animals tongue.

As the wing 18 of the guard member rests against the outer side of the animals mouth in the manner shown in Fig. 1 of the drawing, and as the elbow 10 rests against the strap which is applied about the animals mouth, the distance to which the tube may be introduced into the mouth is limited.

Having thus described the invention, what is claimed as new is:

1. In an instrument of the class described, a liquid container, means for discharging liquid from the container, and a delivery tube leading from the container and between ward section in offset relation to the rear section.

3. In'an instrument of the class described, a liquid container, means for discharging liquid from the container, and a delivery tube leading from the container and between its ends being provided with a lateral offset connecting its forward and rear portions whereby to position the forward portion of the tube in ofi-set relation to the inner portion thereof, the outer portion of the tube being bent between its ends whereby its forward portion will be inclined downwardly with relation to rear portion.

4. In an instrument of the class described, a liquid container, means for discharging liquid from the container, a delivery tube leading from the container and between its ends being provided with a lateral off-set connecting its forward and rear portions whereby to position the forward portion of the tube in off-set relation to the inner portion thereof, and a guard member upon the tube inwardly of the said off-set.

5. In an instrument of the class described, a liquid container, means for discharging liquid from the container, a delivery tube leading from the container and between its ends being provided with a lateral off-set connecting its forward and rear portions whereby to position the forward portion of the tube in off-set relation to the inner portion thereof, and a guard member upon the tube inwardly of the said off-set, the said guard member comprising relatively angu larly positioned wings and one of said wings being formed with an opening to receive the said tube, the other wing occupying a plane beside the tube.

6. In an instrument of the class described, a liquid container, means for discharging liquid from the container, and a delivery tube leading from the container and between its ends being provided with a lateral off-set connecting 1ts forward and rear portions whereby to position the forward portion of the tube in off set relation to the rear portion thereof,'the forward portion of the tube being bent between its ends to extend both downwardly and laterally with relation to the rear end of the said portion.

In testimony whereof I aifix my signature.
